WINDOWMSCREEN.

SPECIFICATION forming part of Letters Patent No. 604,799, dated May 31, 1898. Application filed September 24, 1897. Serial No. 652,897. (No model.)

To all whom t may concern:

Be it known that I, ELWYN SPEAKER, a citi- Zen of the United States, residing at Egan City, in the county of Ogle and State of Illi- :nois7 have invented a new and useful Window-Screen, of which the following is a specication.

This invention relates to guards orscreens for protecting windows and like openings, whereby apartments may be ventilated and liies and like insects excluded, and which at the same time will admit of a portion of the opening being uncoveredavhereby blinds may be reached for opening and closing, objects thrown from the window, and the head protruded for observation.

A further purpose of the invention is the provision of a screen capable of adjustment within certain limits,whereby any-sized opening within the range of adjustment of the screen may be litted and the screen held in place without the use of nails, screws, or like fastenings, which usually mar the easement and, besides, are difficult of insertion to secure the screen in place and of removal when the screen is to be taken out and laid aside after the warm season has passed.

For a full understanding of the merits and advantages of the invention reference is to be had to the accompanying drawings and the following description.

The improvement is susceptible of various changes in the form, proportion, and the minor details of construction without departing from the principle or sacrificing any of the advantages thereof, and to a full disclosure of the invention an adaptation thereof is shown in the accompanying drawings, in which- Figure l is a front View of a window-screen constructed in accordance with this invention, an intermediate portion being broken away. Fig. 2 is a vertical section on the line c of Fig. l, looking to the left, as shown by the arrows. Fig. 5 is a view similar to Fig. l of the reverse side of the screen, one wing and the sliding screen being omitted. Fig. 4C is a plan section on the line yy of Fig. l. Fig. 5 is a detail view of the sliding screen, an intermediate portion being broken away.

Fig. lO is a view similar to Fig. 9 of a lower corner of the sliding screen. Fig. ll is a detail view of the joint formed between a side stile and the middle rail of the main-screen frame.

Fig. 1G is a section on the line c cof Fig. 15.

Corresponding and like parts are referred to in the following description and indicated in the several views of the accompanying drawings by the same reference characters.

The screen is composed of a relatively-iixed section l and a sliding section 2, and is provided with side wings 3, which are adjustable laterally to vary the width to adapt the screen to different-sized windowopenin gs within the range of adjustment of the wings. The up per or fixed section l comprises side stiles 4:, an upper rail 5, and a middle rail G, the latter having dovetailed tenons 7 at its ends to enter corresponding mortises 8 in the inner edges of the side stiles 4, whereby the latter are prevented from spreading. The upper rail 5 has tenons 9 at its ends to enter open inortises l0 in the upper ends of the stiles 4, said tenons being secured in the mortises by brads or in any desired manner. Strips ll are secured to the lower portion of the side stiles 4. and have their inner edges rabbeted to form guideways for the sliding` section 2, and the end portions of these strips are rounded to prevent the sash from catching thereon and damaging or injuring the screen.

The side wings 3 are adjustable laterally to enable the screen to be tted snugly between the stops of the window-frame and are provided on their inner faces with transverse grooves or seats l2, which are under` cut at their edges and inner ends to receive the beveled edges of plates 13 fitted therein, said plates having slots let extending inward from their outer ends. Channels l5 are formed ICO in the bottoms Of the grooves or seats 12 to receive the heads of clamp-bolts 16, by means of which the side wings are securely fastened in an adjusted position. The clamp-bolts 16 pass through openings in the side stiles 4 and through the slots 14 Of the plates 13 and their heads engage with the inner side ofthe plates and hold the win gs 3 in place when the clamp-nuts are screwed home. These side wings correspond in length to the side stiles, so as to prevent the formation of a space when the screen is in position.

The sliding section 2 is composed of a top rail 17, a bottom rail 18, and side bars 19, which are rabbeted at their outer edges to cooperate with the rabbeted edges of the strips 11, whereby the section is guided in its vertical movements. The several rails and bars comprising the frame of the sliding section 2 are tenoned together, as indicated in the detail views, and are secured by brads or other suitable fastenin gs.

The frame-bars of the sections 1 and 2 are rabbeted to receive the Wire screen 20, and strips 21 are tted into the rabbeted portions and over the edge portions of the wire screen to protect the latter and secure it in place, said strips being held in place by brads or in any manner commonly resorted tO for securing like parts. The lower rail of the section 1 will be extended, so as to meet the wire screen of the sliding section, thereby preventing the formation of any space or opening between the two screens which would afford a passage for iiies or like insects. The frame-bars may be reeded or otherwise ornamented to give them a pleasing appearance, and the side stiles and wings will be of a length to fit the largest-size opening, so as to be cut off at their lower ends to iit the screen to an opening of smaller size, the lateral adjustment to accommodate the width of the screen to the Width of the Opening being had by moving the wings, as herein set forth.

The screen can be fitted to the windowframe below the top sash or above the bottom sash, as desired. If the side stiles and wings are too long, they are cut off to the required length, as indicated by the dotted lines at the bottom of Fig. 1. When in position, the bottom screen can be slid up or down to admit of the head Or hand being thrust out through the window-Opening or for any purpose.

Having thus described the invention, what is claimed as new is- 1. In an adjustable screen, the combination of Wings having transverse grooves or seats in their inner faces, and channels at the bottoms of the said grooves or seats, lon gitudinally-slotted plates fitted into the said transverse seats, and clamp-bolts mounted in Openings in the screen and passing through the slotted plates and having their heads Operating in the aforesaid channels, substantially as set forth.

2. In combination, a screen, laterally-adj ustable Wings having transverse grooves formed with undercut edges and inner ends, plates having their edges and inner ends beveled and fitted into the said transverse grooves and having longitudinal slots which extend through the outer ends of the plates, and clamp-bolts passing through Openings in the side stiles of the screen and having their headed ends Operating in the grooves of the wings and slots of the aforesaid plates, substantially as and for the purpose specified.

In testimony that I claim the foregoing as my Own I have hereto affixed my signature in the presence of two Witnesses.

ELWYN SPEAKER.
